The passenger was on flight 107, which was traveling from Seattle to Anchorage on Monday. He reportedly removed his clothes and ran the length of the cabin for about 20 minutes before landing. Two passengers reportedly tackled him and locked him in a bathroom.

An Alaska Airlines representative confirmed to Business Insider that a “disruptive male passenger was detained” by law enforcement after the flight landed at Ted Stevens Anchorage International Airport and taken to a nearby hospital.

“Alaska Airlines flight 107 from Seattle landed without incident in Anchorage,” the representative said. “Shortly prior to descent into Anchorage a disruptive male passenger was detained. He was removed by law enforcement after the plane parked at the gate and was then transported to a local area hospital.”

The representative did not comment on whether the passenger removed his clothes during the flight.

A Ted Stevens Anchorage International Airport representative said local authorities responded to an incident on the flight but did not provide further details.

Johnny Ellis, a former member of Alaska’s Senate and House of Representatives, was on the flight and wrote about it on Twitter.
